This is a pseudo-sufficient assumption question, as the question stem indicates: Which one of the following principles, if established, would most help to justify a doctor’s decision to use drug Z rather than drug Y when treating a patient? Then question stem gives us the information that we need to justify. Let’s see how this appears in the stimulus.

We have information on two studies conducted for drugs Y and Z to prevent blood clots from developing after a heart attack. Y is not more effective than Z (which costs more); but Z could be slightly more efficient or is just as effective as Y. The people who made Z don’t contest these claims but they add that the study does not reveal the added benefits of Z. We’re then told because it’s not clear that Z is more effective than Y, there is no medical reason to prescribe it over Y. Our question stem is asking us to pick the answer that most justifies the reasoning of a doctor who wants to use drug Z (more expensive and potentially slight more effective) over drug Y. A general rule would take evidence from the argument (have it more readily in stock or could be more effective) and put take in the sufficient condition in a conditional with our conclusion in the necessary condition: If they have it in stock/it could be more effective, doctors should prescribe it. Remember that PSAr answer choices do not need to render the argument valid, just somewhere close to it.

Answer Choice (A) doesn’t justify why a doctor can prescribe Z over Y, it justifies a different situation of what requirements patients have to meet in order to be given a drug. This does not justify.

Answer Choice (B) is also incorrect because we’re not concerned with compensation. Deserving something doesn’t justify their choice of Z over Y.

Answer Choice (C) tells us what we should not take into account but fails to mention how we can justify choosing drug Z over drug Y. This is also out.

Answer Choice (D) doesn’t apply to our situation because the drug company doesn’t criticize the findings! It just adds that the findings failed to mention the benefits.

Correct Answer Choice (E): This answer choice is correct; it takes information from the stimulus (potentially more beneficial) and uses it to justify choosing Z over Y.
